Product Description
The MTK MT3117N is a powerful GPS receiver chipset tailored for modern navigation requirements. Its high sensitivity ensures reliable satellite acquisition and tracking, even in areas where GPS signals are weak or obstructed. This is particularly beneficial for applications such as automotive navigation, outdoor tracking, and IoT deployments where consistent performance is critical.
With a focus on energy efficiency, the MT3117N is ideal for portable and battery-powered devices. Its advanced power-saving features allow it to deliver extended operational times without compromising functionality. These features are crucial for devices like smartwatches, fitness trackers, and asset trackers that require prolonged use.
The chipset's fast TTFF capabilities provide quick and reliable satellite acquisition, ensuring a seamless user experience in real-time applications. Whether starting from a powered-off state or resuming from brief signal loss, the MT3117N delivers accurate and immediate positioning.
Its ability to track up to 22 satellites simultaneously enhances the accuracy and reliability of its positioning data, ensuring consistent performance in dynamic environments. The inclusion of A-GPS functionality further improves the chipset's performance, particularly in urban environments where standalone GPS systems may struggle to achieve a fix.
The compact design of the MT3117N simplifies integration into various devices, reducing development complexity and system size. Its compatibility with active and passive antennas offers flexibility in device design, ensuring optimal signal reception regardless of the application.
The MT3117N supports a high update rate of up to 10 Hz, making it suitable for dynamic applications such as vehicle tracking, sports devices, and drone navigation. Its standardized interfaces, such as UART, ensure seamless communication with a wide range of microcontrollers and embedded systems.
